JOHN E. ROWAN AND LOUIS F. BAUIVIAN, OF VIRGINIA, MINNESOTA.

WASHING-BOILER.

Speccation of Letters Patent.

Patented Sept. 30, 1913.

To all "whom t may concern:

Be it known that we, JOHN E. Rowan and Louis F. BAUMAN, citizens of the United States, residing at Virginia, in the county of St. Louis and State of Minnesotar, have invented new and useful Improvements in Washing-Boilers, of which the following is a specification.

The general object of this invention is the provision of a washing boiler adapted to receive articles of clothing therein, whereby the latter may becleansed by injecting Steam into said boiler,n novel means being provided for the escape of the steam after the same has circulated through the clothes.

In carrying out the object of the invention generally stated above, it will be understood, of course, that the essential features thereof are susceptible to changes in details and structural arrangements, one preferred and practical embodiment being shown in the accompanying" drawing,

wherein- Figure 1 is a side elevation Vof the boiler constructed in accordance with the invention. Fig. 2 is a vertical longitudinal sectional view thereof. Fig. 3 Vis a top plan view. Fig. 4L is adetail perspective of the means for permitting the escape of steam from the boiler.

Referring more particularly to the accompanying drawing, in which like reference characters designate similar parts, it .will be seen that the invention comprises a reservoir 5 which is tapered throughout its entire length, said reservoir being pro-vided with a substantially cylindrical portion 6 and a reduced offset portion 7 communicating with said cylindrical portion. The cylindrical portion 6 is provided in the top thereof with a rectangular' opening 8 which is adapted to be closed by means of a door 9, said door, when closed, being adapted to render the reservoir 5 air tight. The outer end of the offset portion 7 has mounted therein adjacent the bottom thereof a'steam inlet pipe 10 which is adapted to be con nected to a suitable Source of steam sup-ply (not shown). After a number of articles of clothing have been placed in the reservoir 5 through the opening 8 therein and the door -9 placed in position, steam is injected into the reservoir through the medium of the pipe 10 and said steam is under sufficient pressure fo-r the same to thoroughly circulate through the said articles of clothing and any condensed steam may pass otl through the drain pipe 11 which is mounted in the bottom of the cylindrical portion 6 of the said reservoir. Adjacent the top of the cylindrical portion 7 and on each side thereof, the same is provided with a plurality of transverse openings 12. Each of the openings 12 is adapted to receive one of the angular extensions 13 of the steam exhaust pipes 14: which extend vertically on each side of the cylindrical portion 6 and which communicate at their lower ends with the pipes 15, said latter pipes extending at right angles to the pipes 1li and longitudinally of the reservoir 5 to a point at the rear thereof. Here the pipes are bent to extend transversely of the rear of the reservoir and are adapted to communicate with an outlet pipe 16. It will thus be seen that after the steam has circulated through the clothing in the reservo-ir the same will rise therein and pass out through the openings 12 into the pipes 14, thence to the pipes 15 and 16 and thence to the atmosphere.

The shape of the boiler lends importance to thestructure in that by reason of the` reduced space immediately adjacent the inlet as compared with the enlarged circular space beyond the same we provide for the reception of the clothes in said circular space and prevent their entrance into the reduced space. By this means steam entering the boiler through the inlet pipe is permitted to expand and thereby reach all of the clothes in the boiler and avoid the disadvantages which would be present inthis stationary type of boiler were steam directed in a single jet against one portion of the clothes only. By this construction we gain advantages of a rotary boiler without necessitating the movement of any part thereof.

From the foregoing description taken in connect-ion with the accompanying drawing, it will be seen that the invention contemplates providing a washing boiler which is simple in construction thus reducing the cost of manufacture of the same to a minimum, and which is durable and effective in carrying out the purpose for which it is designed.

1What is claimed is A wash boiler comprising a receptacle tapered throughout its length and formed to provide a substantially cylindrical portion and a longitudinally alined offset portion in communication with the cylindrical portion, a steam inlet pipe opening into the In testimony whereof We aix your signaofset portion remote from the cylindrical tures in presence of two Witnesses.
